Various CIFS/SMB2/SMB3 updates for 3.11. Includes bug fixes - SMB3
support should be much more stable with key DFS fix and also signing possible
now (although is more work to do to get SMB3 signing working well with
multiuser).
Mounts using the new SMB 3.02 dialect can now be done (specify "vers=3.02"
on mount) against the most current Microsoft systems. Also includes a big
cleanup of the cifs/smb2/smb3 authentication code from Jeff which fixes
some long standing problems with the way allowed authentication flavors and
signing are configured. Some followon patches later in the cycle will clean
up allocation of structures for the various security mechanisms depending on
what dialect is chosen (reduces memory usage a little) and to add support
for the secure negotiate fsctl (for smb3) which prevents downgrade attacks.
The following changes since commit acdb37c361dc87e165889a504e291c1e82ae133c:
